The purpose of this study was to develop a diagnostic test in basic mathematics appropriate for underprepared students. The objectives of the Basic Mathematics Diagnostic Instrument (BMDI) were designed to meet the needs of both basic mathematics instructors and the students who have been identified as needing remediation in basic mathematics. Although the students probably have been identified as having overall deficiencies, the BMDIneeded to produce information which determined specific strengths and weaknesses of each individual in basic mathematics. / Ph.

The purpose of this study was to investigate the relationship between selected basic library skills and the use of the library by freshman community college students, and to determine or evaluate the extent to which the use of the library by such students is related to or influenced by the level of their library skills. The population utilized in this study was the total enrollment of freshman students beginning their second semester of study at two typical Texas rural community colleges, namely Cooke County College at Gainesville, Texas, and Grayson County College at Sherman, Texas. Data regarding library skills were obtained through the use of a standardized test instrument, A Library Orientation Test for College Freshmen. Data regarding library use, relevant demographic traits, and selected control variables (age, sex, hours worked, self-perceived library skills, school attended, a measure of intelligence, marital status, and major course of study) were obtained through the use of a specially prepared questionnaire instrument. Through the use of generalized scattergrams with both present study and pilot study data a possible simple linear relationship was found to obtain between library skills and library use in both instances. Bivariate Spearman correlations were then computed for all variables considered in the present study. Those variables showing a strength greater than 0.10 were "promoted" to Pearson correlation values and utilized as input for a multiple linear regression analysis. A conjectural model was constructed from the output of the multiple linear regression analysis which suggested that, if the direction of influence is ignored, the relative importance of the variables utilized in this procedure would be, from most important to least important, tested library skills, hours worked other than attending school, age, and self-perceived library skills.
